| This article's name is conjectural.|
Although this article is based on official information, the actual name of the article's subject is pure conjecture.
One crusher appears in MeteoTech Premises. It doesn't hurt the player, but blocks the rider's path.
One crusher appears in the episode "Lovesick Sonic", used as a backup trap for Sonic. When Sonic was knocked out by the electricity magnet, he dodged it, also saving Breezie. Scratch refers it as "The Smash Stepper".
Some games have the crusher, but the crusher only acts like a normal hazard, and only kills if one has no rings. However, it goes through invincibilty. Some people have complained when it actually made Super Sonic drop rings.
